1. A display device for a motor vehicle, comprising:
a display screen unit, including:
a display screen element configured as one display surface dividable into a plurality of subareas which respectively display, and
a sight protection element which is a switchable foil or a switchable film having a surface subdivided into a plurality of subareas of the sight protection element that correspond to the plurality of subareas of the one display surface so that a degree of transparency of at least one subarea of the sight protection element, of the plurality of subareas of the sight protection element, is switchable to be set for the at least one subarea of the sight protection element;
a back lighting module including at least one illumination element directed to the display screen unit; and
a controller configured to set the display screen unit in a display mode, in which the sight protection element is switched to set the degree of transparency for the at least one subarea of the sight protection element,
wherein the display mode includes the controller being configured to:
 determine at least one subarea of the one display surface, from among the plurality of subareas of the one display surface, which displays a graphical element, and
 change a degree of transparency of the at least one subarea of the sight protection element corresponding to the at least one subarea of the one display surface which displays the graphical element, from among the plurality of subareas of the sight protection element, so that a degree of transparency of remaining subareas of the sight protection element is different compared to the at least one subarea of the sight protection element which corresponds to the at least one subarea of the one display surface which displays the graphical element, and
 control the at least one illumination element of the back lighting module to illuminate the remaining subareas of the sight protection element, from among the plurality of subareas of the sight protection element based on a movement of the display screen unit from a stowed position to a deployed position.
